Usually a large male will lead a gorilla family. This can be a silverback, and males of 11 or 12 years of age are the ones that go grey in this manner. 5 people found this useful.
Fetal movement will usually be felt regularly after the 20th week of pregnancy. Any change in fetal movement (other than a 1-2 hour sleep cycle that some fetuses have) should be discussed with your physician. Decreased or absent fetal movement may be a sign of fetal distress. Kick tests (fetal movement counts) are used to monitor fetal wellbeing. You should monitor fetal movements (not just kicks) over a period of time (30-60 minutes). There is no right or wrong number of movements. You are trying to establish a baseline of fetal movements for your baby.
FETAL MOVEMENT is the best indicator of fetal well-being. Do your kick counts once a day, preferably in a quiet place with no distractions, and after you have eaten something. You should get 10 kicks within two hours, although most babies will give you that in 15 to 20 minutes.
